An AUTO mode simplifies operation by ensuring proper measurement parameter setup, while a high-contrast color LCD screen display clearly presents the OTDR trace and event table. Expert and novice users can quickly examine fiber characteristics and analyze any anomalies that exceed user defined thresholds, reducing fiber outage and system downtime. In addition, the unit is also equipped with a visible laser to visually troubleshoot bad splices and connectors.

Weighing only 900 g (<1.98 lb), the FX300 series is one of the smallest and lightest mini OTDRs on the market – its form factor is perfectly suited to address the portability and space constraints typical of overhead CATV cable routes, curbside FTTx cabinets and manholes. The ruggedized chassis incorporates a fan and vent free design that prevents dust and moisture ingress, thus it is perfectly suited for the challenging outside plant environment.
